Cable Gland and Connection
The cables have to be fed into the instrument via glands to ensure the increase. Cable diameters of 9…13 mm
for the cable gland M20x1.5 (4x) and 5…9 mm for the cable gland M16x1.5 (10x) are suitable. The conductors
are connected to screw terminals inside the instrument. Max. conductor cross-section 2.5 mm
2
.
The connections are made via plug-in screw terminals. The conductors taken to the terminals shall be as short
as possible. The conductors of each cable must be tied together with a cable strap shortly before the terminal
block.
Caution!
For protection during transport and installation, the cable glands are fitted with a
polyethylene cover.
For full IP protection, operation with the dust protection cover fitted is not
permissible!
If a cable gland is not used, it must be sealed with a supplied blind plug.
Cabling
In principle, the cables can be taken through all cable glands corresponding to the cable diameters. The
following figure shows a cabling proposal.
